SECTION 1 INTRODUCTION 1.1 The WH System 6-24 / 9-32 boilers are a fully automatic, wall mounted, room sealed condensing high efficiency boiler for central heating and hot water with a separate indirect hot water storage cylinder is also incorporated in the system. The system boilers wich incorporates a circulation pump, expansion vessel, safety valve, pressure gauge and electronic ignition. The boilers are equipped with a front cover which can be removed for servicing. The data badge with technical data, Gas Council number, model name and serial number is placed on the lower part of the left hand side panel. 1.2 Fig.1 Illustrates the general layout of components. Fig.2 Illustrates the operating principles described in section 2. SECTION 2 2 DESCRIPTION OF CONTROL SYSTEM AND SEQUENCE OF OPERATION 2.2 Operating mode 2.2.7 The boiler also incorporates an anti-block system which powers the pump every 24 hours, allowing it operate for 2 minutes if the boiler has not been in use. This operation may in some cases be heard for a short period when the pump has been activated. 2.5 Safety device The WH System 6-24 / 9-32 boilers safe operation are ensured by a control board which shuts off the main burner, if the fan stops or the flue or combustion air intake duct is obstructed. 2.5.1 An overheat cut off thermostat acts to turn off the burner to resetable lockout (Fig. 33). 2.5.2 A safety valve is fitted on the primary circuit set at 3 bar. 2.5.3 A low water pressure switch set at 0.4 bar is fitted on heating circuit, to prevent the boiler operating below this boiler system pressure. 2.2.1 With a demand for heating, the pump circulates water through the circuit. 2.2.2 The spark ignition system is powered which in turn commences the spark igniter to operate and light the burner. At this point the ignition board opens the gas valve to light the burner. 2.2.3 When the electrode sensor senses the signal that the burner is alight, the spark igniter stops. 2.2.4 From the fan speed setting the boiler increases to the maximum permissible speed over a period of 5 seconds and will remain at its maximum required power until its maximum regulated temperature is achieved and then will modulate to maintain this. 2.2.5 When the demand is satisfied the burner is extinghished and pump continues to run for a period of 3 minutes. 2.2.6 The boiler is fitted with an anti-cycling device on the control board. This delays the boiler from re-firing within 10 minutes. If the heating temperature goes 20 C below the set point, the burner restarts immediately. 6

The system boiler may be installed in any room or internal space, although particular attention is drawn to the requirements of the current I.E.E. Wiring Regulations, and in Scotland the electrical provisions of the Building Regulations applicable in Scotland, with respect to the installation of the system boiler in a room or internal space containing a bath or shower. Where a room sealed appliance is installed in a room containing a bath or shower, any electrical switch or appliance control, utilising mains electricity should be so situated that it cannot be touched by a person using a bath or shower. A compartment used to enclose the system boiler MUST be designed and constructed specifically for this purpose. An existing cupboard, or compartment, may be used provided it is modified accordingly Samples of the WH System 6-24 / 9-32 boiler have been examined by B.G. Technology Notified Body, and is certified to comply with the essential requirements of the Gas Appliance. Directive 90/396/EEC, the Low Voltage. Directive 72/23/EEC and shows compliance with the Electro Magnetic Compatibility. Directive 89/336/EEC and are therefore permitted to carry the CE Mark. The appliance has been tested and approved by the WRc as meeting the requirements of G3 and L of the Building regulations and water Bylaws Scheme - Approved Products. 4.5 GAS SUPPLY 4.5.1 A gas meter is connected to the service pipe by the Local Gas Region or the Local Gas Region contractor. An existing meter should be checked preferably by the Gas Region to ensure that the meter is adequate to deal with the rate of gas supply required for all appliances it serves. Installation pipes should be fitted in accordance with BS 6891. Pipework from the meter to the boiler must be of adequate size (22 mm) min to within at least one metre of the boiler, (15 mm) min. can then be used for remaining pipe work to the appliance. A smaller size than the boiler inlet gas connection should not be used. The complete installation must be tested for soundness as described in the above Code. N.B. if the gas supply for the boiler serves other appliances ensure an adequate supply is available both to the boiler and the other appliances when they are in use at the same time. 4.6 FLUE SYSTEM 4.6.1 The terminal should be located where dispersal of combustion products is not impeded and with due regard for the damage or discolouration that might occur to building products in the vicinity (see fig. 5). The terminal must not be located in a place where it is likely to cause a nuisance In cold and/or humid weather as water vapour may condense on leaving the flue terminal. The effect of such pluming must be considered. The terminal must not be closer than 25 mm (1 in) to any combustible material For protection of combustibles, refer to BS 5440.1. Where a flue terminal is installed less than 1000 mm. from a plastic, or painted gutter; or 500 mm from painted eaves, an aluminium shield 1000 mm. long, should be fitted to the underside of the gutter or painted surface. Pluming will occur at the terminal so, where possible, terminal positions which could cause a nuisance should be avoided. The flue must be installed in accordance with the recommendations of BS 5440: Part 1. IMPORTANT NOTES For greater flue lengths see alternative flue instructions. Flue must be positioned in a place not likely to cause a nuisance from pluming. 13

FLUE TERMINAL POSITION Fig.5 14

IMPORTANT NOTICE: If the fl ue terminates below a balcony, above the ground, above a fl at roof to which people have access, then a suitable terminal guard must be fi tted PRO110100. Fit only recommended FLUE TERMINAL GUARD by securing concentrically around terminal with screws. Available on request from: The White Boiler Company Morley, Leeds, West Yorkshire ENGLAND LS27 9ET - UK Tel.0044(0)113 252 7007 IMPORTANT: The following notes are intended for general guidance. The boiler MUST be installed so that the terminal is exposed to external air. It is important that the position of the terminal allows the free passage of air across it at all tirnes. Minimum acceptable spacing from the terminal to obstructions and ventilation openings are specifi ed in Fig. 5. Note positions: Due to the terminal design, installation is possible with clearances less than those specifi ed in BS 5440, Part 1 NOTE: The flue must be terminated in a place not likely to cause a nuisance. 4.6.2 A concentric vertical flue kit is available for flueing applications up to a maximum height (see table 3 page 19). For further details see vertical flue installation instructions. 4.7 AIR SUPPLY 4.7.1 The following notes are intended for general guidance. The room sealed fan flued boiler does not require a permanent air vent for combustion air supply. Where installed in a cupboard or compartment ventilation is not required. 4.8 WATER CIRCULATION (central heating) to ensure air is carried naturally to air release points and water flows naturally to drain taps. It should be ensured as far as possible that the appliance heat exchanger is not a natural collecting point for air except where providing useful heat, pipes should be insulated to prevent heat loss and to avoid freezing. Particular attention should be paid to pipes passing through ventilated spaces in roofs and under floors. IMPORTANT. A minimum length of 1 metre of copper pipe MUST be fitted to both flow and return connections from the boiler before connection to any plastic piping. 4.8.3 The water through the appliance heat exchanger circuit must exceed the min. 2.38 gals/min. (650 It/h) when the burner is firing. It is important to ensure that this rate is achieved when sections of the system are shut off either manually or by automatic controls. If the volume of circulating water is too low, the boiler water temperature will rise too rapidly. This could cause noise in the system or even cause the safety thermostat to trip. 4.8.4 BOILER INTERLOCK CONTROL Central heating systems controls should be installed to ensure the boiler is switched off when there is no demand for heating, in compliance with Building Regulations. If the system has thermostatic radiator valves on all radiators, or two port valves, then a bypass circuit must be fitted with an automatic bypass valve to ensure a flow of water should all valves be in the closed position.(see fig. 6). 4.8.5 It is important that the system is flushed thoroughly before the appliance is fitted or left to operate (as recommended in BS 7593) in order to maintain an efficiently operating heating system. For replacement installations, the system MUST be flushed with the old boiler in situ. In order to prevent system debris. Once the system has been flushed, an inhibitor (suitable for stainless steel heat exchanger) should be added. See section 4.8.11. 4.8.1 Detailed recommendations are given in BS6798 2009/5449:1990 - BSEN12828 - BSEN12831 - BSEN14336 (for smallbore and microbore central heating systems). The following notes are given for general guidance. 4.8.2 PIPEWORK. Copper tubing to BSEN 1057:1 2006, BSEN 1172, BSEN 1652 and BSEN 1653, is recommended for water pipes. Jointing should be either with capillary soldered or with compression fittings. Where possible pipes should have a gradient Fig.6 15

4.8.6 Draining tap These must be located in accessible positions to permit the draining of the whole system. The taps must be at least 15 mm nominal size and manufactured in accordance with BS 2870 1980. Fig.7 4.8.7 Air release points These must be fitted at all high points where air will naturally collect, and must be sited to facilitate complete filling of the system. 4.8.8 The appliance has an integral sealed expansion vessel to accommodate the increase of water volume when the system is heated. It can accept up to 8 Its of expansion water. If the appliance is connected to a system with an unusually high water content, calculate the total expansion (see table 2) and add additional sealed expansion capacity as appropriate (Fig. 7).

5.14 SAFETY VALVE DISCHARGE 5.14.1 The safety valve is located to the rear (15 mm copper) to permit a discharge pipe to be connected. When connecting ensure the discharge pipe does not restrict access. The discharge should terminate facing downward exterior to the building in a position where discharging (possibly boiling water & steam) will not create danger or nuisance, in easily visible position, and not to cause damage to electrical components or wiring. The discharge must not be over an entrance or a window or any other type of access. 5.15 CONDENSATE DRAIN CONNECTION 5.15.1 The condensate drain connection is a flexible 3/4 pipe and is therefore adjustable Fig. 31. The drain pipe should have a fall of a least 2.5 away from the boiler. Condensate should, if possible be discharged into the household internal drainage system. If this is not practicable, discharge can be allowed into the external household drains or a purpose designed soak away. It is recommended that any external condensate drain pipe is insulated and also must be of 40 mm (1 1/2) diameter, through the outside wall to prevent freezing in adverse weather conditions. The condensate is discharged periodically in slugs by siphonic action. It is not necessary to provide air breaks or extra traps in discharge pipe as there is already a 125mm high trap inside the boiler. Fitting an extra trap may cause the boiler siphon to work incorrectly. Refer to BS5546 or BS6798 for advice on disposal of boiler condensate. Notes: ALL EXTERNAL PIPE RUNS MUST BE IN ACCORDANCE WITH BS 6798 1 - INTERNAL TO SINK WASTE UPSTREAM OF SINK WASTE TRAP 2 - INTERNAL CONNECTION TO SOIL AN VENT STACK Make connection to SVP using a solvent welded saddle. 30

SECTION 6 COMMISSIONING 6.1 Each boiler has been through a rigorous operational procedure at our factory and should not require any further adjustment, if you are not the installer but just commissioning this boiler check that the boiler has been installed in accordance with these instructions, and the integrity of the flue system and the flue seals, as described in the Flue installation section. 6.2 GAS SUPPLY INSTALLATION 6.2.1 Inspect the entire installation including the gas meter, test for soundness and purge, all as described in BS 6891. In IE refer to IS 813:2002. 6.3 ELECTRICAL INSTALLATION Preliminary electrical systems checks to ensure electrical safety shall be carried out by a competent person. ALWAYS carry out the preliminary electrical system checks: i.e. earth continuity, polarity, resistance to earth and short circuit, using a suitable test meter. 6.4 INITIAL FILLING OF THE SYSTEM Open central heating flow and return valves Unscrew the cap on automatic air release valve positioned on the top of the pump housing one full turn (leave open permanently). - Close all air release taps on the central heating system. - Gradually open stopcock at the filling point connection to the central heating system until water is heard to flow. - Starting with the lowest radiator open each air release tap in turn. Close it only when clear water, free of bubbles, flows out. In the same way release air from any high points in the pipework. - Open the manual air vent at the boiler heat exchanger flow pipe, see fig. 30, may require repeating to assist commissioning. - Continue filling the system until 1.5 bar register on gauge. Then turn off the filling points stopcock. - Inspect the system for water soundness and remedy any leaks discovered. 6.5 SETTING THE HEATING SYSTEM DESIGN PRESSURE The design pressure must be a min. 1 bar and max. 1.5 bar. These figures are read off the pressure gauge. - The actual reading should ideally be 1 bar + the height in metres to the highest point of the system above the base of the appliance (up to max of 1,5 bar). N.B.: The safety valve is set to lift at 3 bar (30 mt/42.5 psi). - To lower the system pressure to the required value remove at the drain point (fig. 35) or drain on the heating circuit. 6.6 LIGHTING THE BOILER Before lighting the boiler make sure that the heating circuit flow and return valves are open. Make sure that the external control, by switching wire (Line), are call for heat. (Sect. 8.24) IMPORTANT: Before switching on the boiler POWER SWITCH FOR THE FIRST TIME when commissioning, turn the heating control knob (Fig.33) DOWN TO ITS MINIMUM setting leaving it at minimum for approx 5 mins to purge air safely from the boiler heat exchanger. GAS VALVE Fig. 35 Fig. 34 33

- Turn control knob (Fig.33) down to its minimum setting. - Push the power main switch to on (Fig.33) - The digital display will show water set point temperature in central heating. - The fan starts and after a second or so the digital led display will show that the ignition has commenced. - NOTES : It maybe necessary to reset the Digital Timer on boiler (if fitted) to start. Put the timer to on position (Fig.33). -The ignition control will automatically have three attempts, but initially this may be due to air in the gas supply line.if the burner fails to light, the digital led display and fan will stop, and the display will show the lockout code. -If necessary push the boiler Reset button (Fig.33) and the boiler will restart automatically. - After the boiler has lit, allow to warm at minimum temperature setting to purge any air from the system. - Once the system has been purged of air turn the control knob to the desired position. With leak detection fluid test for gas tightness of all gas components and joints.see paragraph 6.14 for regulating the heating circuit control knob. 6.8 CHECK THE GAS PRESSURE Check the gas mains pressure at the gas valve inlet pressure test (Fig.34) with boiler operating. Check with the Local Gas supplier if the pressure differs significantly from 20 mbar G20 (natural gas), 37 mbar G31 (propane) and 29 mbar G30 (butane). IMPORTANT : the Gas Valve Throttle adjuster is required to be sealed with tamper proof paint after adiustment (fig. 34). 6.9 COMBUSTION CHECK Unscrew the test sample screw on the boiler elbow bend (Fig.10 item 60). Measure the level of CO 2. Check the reading against the corresponding value in sect.3 TECHNICAL DATA. If adjustment proves necessary then proceed as follows. IMPORTANT : Any adjustment to the gas valve should only be carried out by a qualified person. Refer to tables 1/A, 1/B, 1/C and 1/D section 3 adjust the maximum level of CO 2 by turning the Throttle (allen screw 2.5 mm) on the gas valve (Fig.34). Anti-clockwise to increase CO 2. Clockwise to decrease CO 2 After any new regulation wait to stabilise about one minute. - Replace the sample point screw on the flue manifold ( Fig.10 item 60). - Replace the front panel of the case. IMPORTANT: do not insert analyser probe into the sample point immediately or for long periods. This will prevent saturation of the analyser. During the calibration function the combustion ratio may increase for short time while the boiler performance is optimised. The person carryng out a combustion measurement should have been asessed as competent in the use of a flue gas analyser and be able to interpret of the results. The flue gas analyser used should be one meeting the requirements of BS7927 or BS- EN50379-3 and be calibrated in accordance with the analyser manufacturer s requirements. Check gas carrying components along with, the combustion of the appliance which should be checked as follows. Remove the front panel of the case.
